Further, a touch switch chip 700 is further included, and the touch switch chip 700 is connected to the communication and control module 400 and the AC/DC conversion module 100, respectively.
Further, an indicator light 800 is also included, and the indicator light 800 is connected with the communication and control module 400.
Further, the communication and control module 400 includes a control processing chip, model BK 7321U.
Further, the sampling and metering module 200 includes a high-precision metering chip, model HW 8012.
The design scheme of the WIFI + BLE chip intelligent switch adopting the BK73 7321U is solved by adopting a WIFI + BT two and one mode, and has the advantages of high stability, low standby power consumption, long transmission distance and the like. The user can control and monitor the working state of household appliances at any time and any place through the intelligent switch, and inquire the electricity utilization information of the household appliances. And meanwhile, when an electrical appliance number store in the house is abnormal, the intelligent switch can automatically cut off the switch. The corresponding APP of the mobile equipment such as the mobile phone controls the electricity utilization information of the whole family and the household appliances.
The intelligent product in the past is 433, infrared, also be wiFi at most, and this product of I now is the two unification intelligence switch of WIFI + BLE, have wiFi get into the wide area network with gateway UNICOM, and every switch (intelligent product) of family all can the bluetooth MESH network deployment, the core problem that gateway and signal cover have then mainly been solved to the bluetooth MESH agreement, equipment based on bluetooth MESH agreement no longer relies on the gateway, every equipment has still played the effect of expanded network when realizing self function, support multinode interconnection between each equipment simultaneously, can not influence whole network because of the damage of single equipment, control end (computer, cell-phone or intelligent audio amplifier etc.) just can be with controlling the global in the signal range of arbitrary equipment just appearing. In short, it is two points: 1. the gateway 2 is not used, and the coverage is wider and more stable as more devices are used. Besides the advantages of signals, the equipment of the Bluetooth MESH protocol has the advantages of low power consumption, strong anti-interference capability, low cost and the like.
